MEASURING STEAM-TRAP.

SPECIFICATION forming part of Letters Patent No. 397,184, dated February 5, 1889.

Application filed March 29, 1888.

To all whom it may concern:

Be it known that I, GEORGE GUNTZ, a citi- Barr, in the county of Luzeruc and State of Pennsylvania, have invented certain new and useful Improvements in Measuring Steam- Traps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to steam-traps; and it consists in the novel construction and com bination of the parts, as hereinafter fully described and claimed, whereby the amount of condensed water expelled from the trap may be ascertained.

This trap is intended for use in connection with steam-heating coils for dwellings which are supplied from a centrally-located boiler common to all the dwellings included in the system. The amount of steam used by each separate dwelling may be approximated from the amount of condensed water expelled from the steanrtrap in'each dwelling.

I11 the drawings, Figure 1 is a side view of the trap. Fig. 2 is a vertical sect-ion taken on line 2 2 in Figs. 3 and 6. Fig. 3 is a vertical section 011 line 1 1 in Figs. 1 and at. Fig. at is a plan view of the trap from above. Fig. 5 is a sectional plan view taken on line 3 3 in Figs. 1, 2, and 3. Fig. 6 is a plan view of the trap with the cover removed.

A is the inclosing-case of the trap, and a. is a removable cover secured to the top of the case.

Bis the valve-casing secured at the bottom of the case and provided with the annular orifice b and the discharge-opening I).

C is a cylindrical discharge-valve sliding vertically in the casing B, and a is the inletopening for steam and condensed water in the upper part of the inclosing-case A.

D is the valve-stein pivoted to the valve by the pin cl, and D is a plate provided with a slot, d, which is secured to the upper end of the valve-stem.

E is a lever provided with the weight E for counterbalancing the weight of the valve, its stem, and the slotted plate. The lever E is pivoted to the upper end of the said plate by the pin 6. 1

Serial No. 268,815. (No model.)

F is a bracket secured to the case A and provided with the pinf, upon which the lever E is pivotally supported.

G is a rock-shaft journaled in the casing, and g is a bell-crank lever secured upon the said shaft and provided with the weight G and the pin g, which passes through the slot d.

H H are vertical rods pivoted upon the ends of the pin g and provided with the collars h.

I is a float provided with the vertical tubes '2, sliding over the valve spindle and the rods H. p

J is a small crank upon the end of the rockshaft outside the casing, and j is a pawl which operates the ratchet-wheel j of the register K, which is provided with pointers, marked dial-' plates, and toothed gearing, all of which are of ordinary construction, such as are in common use for gas-meters.

The operation of the device is as follows: The steam and condensed water enter by the inlet a and the float rises as the water accumulates, and thereby raises the rods H by hearing against the upper collars h. This action also turns the bell-crank, but does not affect the valve-stem. hen the weight G passes the center of the rock-shaft, it overbalances suddenly and falls against the side of the case or against a stop secured thereto. The pin g comes in contact with the top of the slot (1 and pulls the valve 0 suddenly wide open. Each motion of the rock-shaft is indicated by the register, which is operated by the crank J. The condensed water now drains out through the open valve or is forc ibly expelled by the pressure of the steam. The float descends and presses on the lower collars 72 This turns the bell-crank, but does not close the valve until the weight G passes the center of the rock-shaft, when the said valve is suddenly closed by the overbalancing-weight.

It will be seen that the movements of the valve are practically instantaneous, and that the same amount of condensed water will be expelled from the trap each time the valve is opened and the register operated.

\Vhat I claim is 1. In asteam-trap, the combination, with an inclosing-case, of a discharge-valve, a bell crank lever pivoted in the case and provided with a weight, a slotted plate, and pin-connection interposed between said valve and lever, whereby the valve may be operated suddenly by said weight, a float, a rod nevided with t 3 inelosingease, a float in the ease, a d'iseharg'ecollars and arranged intm'mediatebetween the said tloat and bellreranlc. lever, whereby 1 the said weight may be overbalaneed eaeh time said lloat reaehts its highest and. lowest positions, and a registeraeti'iated at eaeh discharge of liquid from the ease.

2. In a steam-trap, the combination ol an in olosin g-ease, a float in the ease, a dischargevalve, a slotted plate secured to the said valve, a weighted bell-crank mounted on a roek'shaft and provided with a pin gi ng with the slot in the said plate, a regis ,er operated by the motion of the rock-shaft. simultaneously with. the opening ot' the valve, and

a rod n'ovided with eollars above and below ease and provided with a pin engaging" with the slotin the said plate, and the rods pivoted on the ends of the said pin and provided with the Heat and eonneeted to the bell-erank, whereby an equal volume of water may be d is charged at each opening of the valve.

in a steam-trap, the combination oi. an inelosing-ease, a tloatin the case, a disehargevalve at the bottom of the ease, a slotted plate, and a stem seeureifl to the valve, a eonntier-balance for the w( g'ht oi the said valve,

its stem, and the plate, a weighted bell-erank I mounted on a rook-shaft and provided with a pin engaging with the slot in the said plate, a register operated by the motion of the rockshaft simultaneously with the opening" ot' the valve, and a rod provided with eollars above and below the float and connected to the bellcrank, so that the water maybe discharged intermittently in equal volumes.

4-. In ast .-am-trap, the combination of an valve, :1 slot-ted plate seeured to the said, valve, a weighted bell-(rank lever pivotally sup ported in the ease and provided with a pin engaging" with the slot in the said plate, and a rod eonneeted to the said pin and provided with eollars above and below the float, where by the said valve may be intermittently opened and closed.

In a steam-trap, the combination of an inelosing-ease, a heat, a diseharge-valve, a slotted plate, and a valve-strait seenred to the valve, a eounter-ltalaneefor the weightol the valve, its stem, and the plate, a weighted.

bell-erank lever pivotally supported in the eollars above and below the lloat, so that the said valve maybe open ed and 0] osed suddenly when the Heat reaches its highest and lowest points, snbstt'mtially as and tor the purpose set forth.
